RESILIENT WHEEL.

Application filed May 24,191.5.

To all Vit/wm t may Concern Be it known that l. JOHN E. Dnnrronovsnr, acitizen of the United States, and resident of Milwaukee, in the countyof Milwaukee and State of Wisconsin, have invented new and useful`improvements in Resilient Wheels, of which the following is adescription. reference being had to the accompanying drawings, which area. part of this specification.

The invention relates to resilient wheels.

The invention designs more particularly to provide a new and improvedform of resilient wheel of the type consisting of a movable outer hubmember, an inner hub member concentrically arranged with respectthereto, and cushioning means between said members for resisting inwardand outward movement of said members with respect to each other and thusforming a wheel which is especially adapted for use as the front wheelof a vehicle.

rThe invention further designs to provide a wheel of the type describedin which the cushioning means consists of solid rubber blocks,preferably cylindrical, disposed in pockets formed by the inner andouter hub members.

rlhe invention further designs to provide a new and improved form ofresilient wheel.

rlhe invention consists in the several features hereinafter set forthand more particularly defined by claim at the conclusion hereof.

In the drawings, Figure 1 is a view of the device embodying theinvention, parts beingbroken away and parts being shown in section; Fig.2 is a section taken on line 2 2 of Fig. 1.

The device comprises an inner hub member A, an outer hub member Bconcentrically arranged with respect to said inner member, andcushioning means interposed between said members to permit said membersto move with respect to each other without shock.

The inner hub member A consists of an axial bore 3 for securing saidmember upon the axle of the vehicle, said b ore having enlarged ends land 5. A. central web 6 extends outwardly from the hub portion 3 andcarries a rim 7. rEhe web 6 is further reinforced by webs 8 and 9extending from the .rim 7 and hub 3 oneither side of the Specificationof Letters Patent.

central web. rlhe periphery of the rim 7 is divided into a plurality ofconcavities 10 for the purposes hereinafter described.

The outer wheel member B consists of an annular ring 11 having atransversely extending rim portion 12'whose inner periphery is providedwith a plurality of concavities 13 for purposes hereinafter described. Ahub cap member 14e incloses the outer end of the inner hub member andits annular portion 15 forms a guide for the flanges of the inner memberand the outer portion 16 of said cap is secured to the transverselyextending rim portion 12 of the member B bv bolts 17 passing through theringl 11 and through the cap and secured in place by nuts 18. A hubplate 19 rigidly secured to the hub portion 5 serves as a guide for thering` 11. The ring 11 and the rim 12 together with an annular ring 20form an annular receiving pocket for the spokes 21 which are securedtherein by bolts 22 and the ring 2O is also held in position by anextension 23 on the cap member 111.

The concavities 10 on the rim 7 of the inner member A and theconcavities 13 on the rim 12 of the outer member B are oppositelydisposed with respect to each other to form a plurality of pockets 24and cushioning means are disposed within each of said pockets. T hismeans consists of a plurality of solid rubber blocks 25. preferablycylindrical, in cross section, which are positioned in the pockets 24formed by the concavities 10 and 13 of the wheel member so that anymovement of these members with respect to each other is cushioned by theyielding rubber interposed therebetween.

The invention thus exemplifies a resilient wheel comprising` movableinner and outer hub members and a plurality of cushioning meansinterposed between said members.

What I claim as my invention is ln a resilient wheel, the combination ofan inner hub member having a rim provided with a plurality ofconcavities on its outer periphery, an outer hub member concentricallydisposed with respect to said inember and comprising,` an annular ring'and a rim extending' tran versely from said ring and having a pluralityof concavities on its inner periphery, the concavities on said rimsforming a plurality of radially disposed a guide for the other side ofthe rim of the inner hub member, and a plate secured to said inner hubmember, forming a guide for the ring of the outer hub member.

In testimony whereof, I aflix my signature.

JOHN B. DRAHONOVSKY.
